SHUTTLE FEELER, FOR LOOMS.

Application filed October 12, 1925. Serial No. 61,970.

To all whom it nmy concern.

Be it known that l, Ham-1r A. DAVIS, a

citizen of the United States, and a resident of Hopedale, in the countyof Worcester and State of Massachusetts, have invented an improvement inShuttle Feelers for Looms, of which the following description, inconnection withthe accompanying drawings, isa specification, likecharacters on the drawings representing like parts.

This invention relates to shuttle feelers for looms.

In looms of the filling replenishing type it is now the usual practiceto provide a shuttle feeler which, on call for replenishment of filling,is moved to a rearward shuttle-feeling position to determine whether ornot the shuttle has been fully boxed, and on failure to be so'fullyboxed, to prevent operation of the filling replenishing mechanism.Should the shuttle not have been properly boxed, the metal end of theshuttle feeler will contact with the shuttle itself, and under suchconditions is liable to Furthermore, should the filling be caughtbetween the end of the shuttle feeler and the shuttle, it is liable tobe broken or ruptured to such an extent as to cause filling failure onsubsequent picks of the shuttle. It frequently happens that a shuttlemaybe properly boxed; i. e., may enter the box fully and the shuttlefeeler consequently move to its full rearward shuttle feeling positionin front of the inner end of the boX, but under such conditions shouldthe shuttle rebound it will engage the side ofthe shuttle feeleradjacent the shuttle box, and since theshuttle feeleris formed of metal,no injury is done.

One of the objects ofthe present invention is to provide a shuttlefeeler with a shuttle engaging end formed of material which willnot-injure the shuttle should the shuttle feeler enga 'e an improperlyboxed shuttle. Owing to the character of the material forming theshuttle engaging end of the shuttle feeler, should the filling beclamped between the body of the shuttle and the end of the shuttlefeeler, it' will not be broken or ruptured or crushed as heretofore, andconsequently the loom may continue to run without broken filling.

As hereinbefore noted,a shuttle will sometimes rebound in the shuttlebox after'the Shuttle feeler has moved to itsifull rearward .the bolt orstud 3.

position, and the present invention further provides a metal contactforimpact by the end of the shuttle in case of rebound. Such metal impactmember is preferably formed as a cover plate overlying the side of theyielding material forming the end of the shuttle feeler, and is sorelated to the yielding end of the shuttlefeeler as not to engage thefilling should the latter be clamped between the yielding materialforming the end of the shuttle feeler and the shuttle bodyof animproperly boxed shuttle;

The invention and novel features thereof will best be made clear fromthe following description and the accompanying drawings of one good formthereof.

In the drawings:

Fig. l is perspective View of the parts upon a bracket 1 secured to theloom frame on which the shuttle feeler 2 is pivoted. as by If desiredthe shuttle feeler 2 may be mounted for pivotal movement in the guidewayformed by the guiding members 4 and :5 supported from the loom Thelay 6may be of usual construction and have mounted thereon the usual shuttleboX 7 for the reception. of the shuttle 8, in which the filling carrier9 is mounted. The parts so far described may be of usual constructionand be operated in the usual'mannerv to cause the 'feoler to moverearwardly into shuttle feeling position to determine whether or not theshuttle has been properly boxed. I

In accordance with the present invention, the shuttle engaging end ofthe shuttle feeler is formed of material, such, for instance, asfibroid, rubber or the like, which may engage the body of the shuttleshould the latter not be properly boxed,.and'yet not injure the shuttle.In the present instance of the invention, the shuttle feeler 2 isprovided with the fibroid shuttle engaging end which has the upper andlower jaws 11 and 12 constituting guiding means for the filling, andalso impact members for engagement with the shuttle should it be notproperly boxed. As shown more fully in Fig. 2, the rear end portion ofthe shuttle feeler is proYided with an opening or cut-away portion, asat 13, forming a tongue let to which is fitted the non-metallic endportion, 10 of the shuttle feeler. The particulars of detail in thisconnection, however, are not important, since such details may be variedwithin wide limits; but the construction described prorides shoulderportions 15 and 16 on the metal portion of the shuttle feeler againstwhich the cooperatingshoulders of the nonmetallic end may rest.

overlying the material forming the end of the shuttle feeler is a coverplate 17 which may be secured in position by any appropriate means; oneform of which, as indicated in Fig. 3, consists of pins 18 which may beutilized not only to secure the cover plate 17 in its overlying relationto the nonmetallic material 10, but likewise also-secure the yieldingmaterial 10 forming the end of the shuttle feeler in place. The pins 18,are preferably formed as rivets or pins having expanded ends flush withthe surface of the cover plate 17 to offer no obstruction to the propermovement of the shuttle feeler into rearward feeling position.

The rear edge portions of the cover plate are in general conformationwith the jaw portions of the non-metallic material 10 forming the end ofthe shuttle feeler, but the edges of the cover plate do not extendrearwardly as far as do the corresponding edges of the yieldingmaterial, with the result that not only does the cover plate not engagethe shuttle should it be improperly boxed, but no injury is done thefilling should it be caught between the improperly boxed shuttle and theend of the shuttle feeler. As shown, the edges 19, 20,, 521 and 22 ofthe cover plate correspond to the similar edges constituting the jaws ofthe nonmetallic material 10, but, as will be evident from Fig. 2, theedges 19, 20, 21 and 22 of the cover plate are not flush with thecorresponding edges of the yielding material, and, consequently, do notengage either the shuttle or filling when the shuttle feeler ismoved toits rearward feeling position.

The metal cover plate 17 is primarily for the purpose of taking theimpact of the end of the shuttle8 should the latter rebound in its box,av condition indicated in Fig. 3, where it will be noted that the end ofthe shuttle engages. the metal cover plate 17 which thereby protects thenon-metallic material from injury by the end of, the shuttle.

It is common at the present time to proyidc the shuttle feclcr with athread partcr or a thread partcr and clamp, and while such parts may ormay not be employed in connection with the present invention, they areshown associated with the shuttle l't-clcr in Figs. 1 and 3. Since,however. the thread parter 23 and thread clamp 2t form no sential partofthe present intention and may operate as usual, further description. ofthese elements will be unnecessary.

From the construct ion dc--ribe l as a good practical form (ii the presinvention, it will be apparentthat the end of the shuttle fecler isformed of material which may czn "e the shuttle without injui; thereto,or

, g'e the i'illing bet n itself and the slnule when the latter aimproperly boxed without crashing or cell ing the Filling, since theyielding material itself presents a non-cuttingsnrface contact. Thecover plate which OYClllQS the non-metallic material 10 at the side nextto the shuttle box provides a metal contact for the end of the shuttleshould the latter rebound in the box it being noted hat the edges of thenon-metallic material 10 project rearwardly beyond the correspondingcdges of the cover plate. ll'hcn the shuttle feeler is in its rearwardshuttle feeling position and the shuttle rebounds, the end of theshuttle will engagi c the plate 17 at a point opposite the backingportion lat formed in the metal of the shuttle feelcr itself and therebyfurther sustain the impact of the shuttle.

hat is claimed is:

1. A shuttle fecler having a tip of nonmetallic material formed withjaws to (fillbrace the body portion of an improperl boxed shuttle, and ametal cover protection plate secured to the shuttle feeler and overlyingthe side of the non-metallic tip next to the adjacent shuttle box to beengaged by the shuttle should it rebound.

2. A shuttle feeler having a tip of noninctallic material securedthereto. and a metal cover plate secured to the shuttle feelcr andoverlying the non-metallic tip at'the side next to the adjacent shuttlebox to receive the. impact of the shuttle should the latter rebound.

3. if. shnttle fccler having a fibrous shattle engaging end, and a coverplate secured to the shuttle feeler and overlying the fibrous end at theside adjacent the replenishing shuttle box, for engagement by arebounding shuttle.

5. A shuttle feeler having a tip of nonmetallic material fornon-injurious contact cover 5 with an improperly boxed shuttle andpresenting a non-cutting surface contact with the filling should it becaught between the feeler and shuttle, and a metal cover plate securedto the shuttle feeler and overlying the tip of non-metallic material atthe side next to the replenishing shuttle box.

'6. A shuttle feeler having a tip of fibrous material formed withshuttle engaging jaws, and a cover plate secured to the shuttle feelerand overlying the tip of fibrous ma terial on the side thereof next tothe replenishing shuttle box. V

7. A shuttle feeler having a tip of nonmetallic material formed withshuttle engaging jaws, and a cover plate secured to non-metallicmaterial on the side thereof next to the replenishing shuttle box, therear edge of the tip of non-metallic material be- Li 8. A shuttle feelermovable to its rear- Ward shuttle feeling position on call forreplenishing of filling and having a non-metallic shuttle engaging endformed with jaws, and a cover plate secured to the shuttle feeler andoverlying the side of the non-metallic end next to the replenishingshuttle box to protect the non-metallic end from contact by a reboundingshuttle.

In testimony whereof, I have signed my name to this specification.
